Trimethyloxonium tetrafluoroborate (TMO) is applied as derivatising reagent to transform urinary organic acids into their methyl esters. The method is suggested as an alternative to the use of diazomethane which is carcinogenic and explosive. In contrast to other methods avoiding

A method for the determination of the organic acids directly in the urine employing derivatization with trimethyloxonium tetrafluoroborate as a methylating agent and sequential extraction by head space and direct immersion/solid phase microextraction is reported. Furoic acid, hippuric acid, methylhippuric

The present work describes the validation of a novel aqueous in situ derivatization procedure with trimethyloxonium tetrafluoroborate (TMO) as methylating agent for the simultaneous, quantitative analysis of Δ(9)-tetrahydrocannabinol (THC) and 11-nor-Δ(9)-tetrahydrocannabinol carboxylic acid (THC-COOH) in human urine. The derivatizing agent

The toxin was treated with [14C]trimethyloxonium tetrafluoroborate or [3H]glycine methyl ester in the presence of 1-ethyl-3(3-dimethylaminopropyl) carbodiimide. Esterification of separate carboxyl groups with [14C]trimethyloxonium tetrafluoroborate decreased the toxicity no more than two-fold. Blocking of any single carboxyl group with [3H]glycine
